I am trying to run a Dash app using a Python index.py file and keep getting an ImportError connected with the dash_core_components library.

I have tried uninstalling and reinstalling Flask and jinja2 and this did not fix the problem.

Traceback (most recent call last):
  File "/Users/lukeneuendorf/nfl_dashboard/index.py", line 1, in <module>
    import dash_core_components as dcc
  File "/opt/anaconda3/lib/python3.9/site-packages/dash_core_components/__init__.py", line 1, in <module>

I was running it without a venv, so I created one. After downloading all the libraries it works now.
